4. Farmers who committed
suicide

5. Reasons
• Climatic conditions
• Politics
• Lack of energy

7. Law of conservation of energy :
“Energy can neither be created nor destroyed but it
can be converted from one form to another form”

9. HISTORY OF ELECTRICITY
• Many people think
Benjamin Franklin
discovered Electricity
with his famous kite-
flying experiments
in1752
• But electricity was not
discovered all at once

10. THE BATTERY
• In 1800, Alessandro Volta , an
Italian scientist, made a great
discovery.
• He soaked paper in salt water,
placed zinc and copper on
opposite sides of the paper,
and watched the chemical
reaction produce an electric
current.

11. • Volta had created the first electric cell.
• By connecting many of these cells together,
Volta was able to “string a current” and create
a battery.
• It is in honor of Volta that we measure battery
power in volts.

12. A CURRENT BEGAN
• An English scientist, Michael
Faraday, was the first one to
realize that an electric current
could be produced by passing
a magnet through a copper
wire.
• Almost all the Electricity we
use today is made with
magnets and coils of copper
wire in giant power plants.

13. Types of energy sources
o Renewable
o Non renewable

14. Types of non renewable energy
resources
o Coal
o Petrol
o diesel
o Natural gas

15. Disfavors!!!
o extinction of resources
o Increasing demand
o pollution

17. TYPES OF RENEWABLE ENERGY SOURCES
o Solar energy
o Wind energy
o Tidal energy
o Geo thermal energy
o Bio mass

18. here comes the SUN
Solar energy is the radiant light and heat from
the sun

19. The total solar energy available to earth is
approximately 3850 ZETA joules per year

20. Facts about solar energy.
• Earth surface receives 1.2x1017 W of power
from sun.
• Energy supplied by the sun in one hour is
almost equal to the amount energy required
by the human population in one year.
• Most if the other source on renewable energy
have their in sun.

21. Why Solar Energy.
• Solar energy is the most readily available
source of energy.
• It is free.
• It is also the most important of the non-
conventional sources of energy because it is
non-polluting.

24. Developments in solar cells
 First generation – pure silicon,33%efficiency,
more expensive
Second generation -- thin film solar cells low cost
low efficiency, CdTe , selenium , amorphous silicon
 Third generation– low cost high efficiency

26. SOLAR ENERGY
Solar energy
is the energy
gained by
capturing
light and heat
emitted by
the Sun.

27. Solar Energy
It is called renewable energy to the
It is a so-called renewable energy obtained from natural sources

group, known as clean
energy or green energy. The sunflower is the icon of renewable
energy by harnessing its great sunlight
and its "similar" to the Sun

28. TYPES OF SOLAR ENERGY
•Passive Solar
Energy: Harness
the sun's heat
without
mechanisms or
mechanical
systems.

29. TYPES OF SOLAR ENERGY
•Solar Thermal
Energy: To produce
low-temperature hot
water for sanitary
and heating.

30. TYPES OF SOLAR ENERGY
•Solar
Thermoelectric
Energy: To produce
electricity with a
conventional
thermodynamic
cycle from a high
temperature heated
fluid (thermal oil).

31. TYPES OF SOLAR ENERGY
•Solar Hybrid Energy:
combines solar energy
with other energy.
According to the
energy with which is a
hybrid combining:
-Renewable: Biomass,
wind power.
-Fossil.

32. TYPES OF SOLAR ENERGY
•Solar Wind Energy:
Works with the air heated
by the sun, which rises
through a chimney where
are the generators.

33. TYPES OF SOLAR ENERGY
•Photovoltaic Solar Energy:
It's a way of obtaining
electricity through
photovoltaic panels.

34. Current growth in the
Solar photovoltaic
is limited in
2006 for lack of subject
premium (so-grade silicon
lar) in the market.

35. The burning of rice husk is obtained
18% of ash containing 92 percent
silicon.

36. Photovoltaic cells convert the sun's
radiation directly into electricity,
using the conductive properties of
silicon.

37. PHOTOVOLTAIC MODULES
A photovoltaic module generates electricity that can be used
directly or stored in batteries for later use.

38. Spain is currently one of the world producers of photovoltaics with an
installed capacity of 3,200 MW estimated, behind Germany, which has
3,800 MW.

39. OUTLINE OF THE FABRICATION OF A SOLAR PANEL

40. The first photovoltaic solar panel arrived in Spain was in the year 1978 and is manufactured
in the U.S., after three decades and is in perfect condition.

41. HY-BIRD: First airplane that will go around the world using only renewable
energies, hydrogen-powered and photovoltaic solar energy. Solar cells are
located in the wings.

42. Satellites with photovoltaic panels to send
energy from space to Earth. NASA and
Japan already studying install 1 km2 of
solar panels in orbit in a year that will
produce more energy than all the known
oil reserves.

43. At the end of the
lifetime of solar
panels, can be a
difficult pollutant
recyclable waste
today.

44. We must seize
energy from the sun by
capturing light and
heat issues.
